Okay I may be lost here..but given the current toolsets of many professions and the things in the DB available to various professions / breeds..
I'm not sure I understand why people are so interested in the mines for Engies given there's so *many* ways to defeat them, or bypass them, in which case their purpose is defeated.
I mean...really...is this just one of those things added in for the sake of adding in or am I missing something? I'm not being sarcastic here..not really..I'm just really confused as to how these could be in any way shape form or fashion useful to a Engie when they're so easily defeatable/bypassed.
